CARL RESCH, OF VIENNA, AUSTRIA-HUNGARY.

BOOT-TREE.

To all whom it may concern:

Be it known that I, CARL Rnscrr, subject of the Empire of Austria-Hungary, residing at Vienna, in the Empire of Austria- Hungary, have invented certain new and useful Improvements in Boot-Trees, of which the following is a specification, reference being had therein to the accompanying drawing.

The present invention has for its object a tree for boots and shoes which is characterized by the form of its constituent parts and the construction of the extender device in such a manner that the tree is extended by actuating a screwthe head of which bears on the front side of the middle element of the tree and which engages in a cross member rotatably mounted between the walls of the rear portion and forming the nut guide.

In the drawing Figure l is a side elevation of the invention. Fig. 2 is a vertical median section of the device, as seen in Fig. 1. Fig. 3 is a plan view, partly in section, on the line BB, of Fig. 2. Fig. 4, is a cross section on the line CC, of Fig. 2, and Fig. 5, is a cross section on the line DD, of Fig. 2.

The three hinged parts a, b, 0 of the boot tree are pressed from sheet metal such as sheet aluminium; the part a corresponding to the fore portion of the foot is open below and is provided with a horizontally directed flange (Z in order to avoid injury to the inner surface of the sole and in order to stiffen it, as shown in Figs. 2 and 3 and particularly in Fig. 5. The middle or frame part b is pressed from a single piece of sheet metal, the free edges of which after suitable forming come upon the under side of the part; they are chamfered overlapped and united by soldering or riveting or Specification of Letters Patent.

pressed out of one piece. The rear part c of the boot tree which produces the actual stretching is hinged to the middle part .7) in proximity to its upper end at 6 and for the purpose of producing the tension its upper short arm is drawn against the middle part Z); this is effected by means of a draw screw f the head m of which bears against the outer side of the part .7), while its shank engages in a cross member h rotatably mounted between the walls of the rear part 0.

Owing to the arrangement that the rearpart 0 is hinged to the middle part b in proximity to the upper ends of the two parts I), c by slightly tightening the tenslon screw f a relatively large displacement of the rear part is obtained (see position indicated in broken lines in Fig. 2). As the handle m of the tensioning screw f rests upon that portion of the front of the middle part b which projects above the boot when the device is in use, the extension of the device obtained by rotating the screw can be efiected without bending or deforming any part of the boot.

Having now described my invention, what I claim and desire to secure, is,

A boot tree composed of vertically separated members, hinged to each other at their upper ends, one of said members being perforated horizontally, the other member having a rotatable bar provided with a threaded opening in line with said perforation and a bolt passing through said perforation and engaging said threaded opening to expand and retract said parts.

In testimony whereof I aflix my signature in the presence of two witnesses.
